HAND AND FOOT MOTOR.

SPECIFICATION formingpart of Letters Patent No. 229,739, dated July 6,1880.

Application filed January 14, 1880.

To all whom it may concern:

Be it known that I, DELOS W. Mom, at citizen of the United States,residing at Hampton, in the county of Franklin and State of Iowa, haveinvented a new and useful Hand and Foot Motor, of which the following isa specification.

My invention relates to that class of motors wherein the hands and thefeet of the operator are employed for imparting power tooperatemachinery.

l attain the object of my invention through the instrumentality of themechanism illustrated in the accompanying drawings, in which Figures 1,2, and 3 are perspective views of my improved motor.

In the several figures, A indicates a rectaifgular foundatiomframe ofthe machine, provided with central uprightsupports, b b, in which acrank-shaft, B, has its hearings, as shown, and having a balance-wheel,0, upon one of its ends, while at its opposite end it is provided with agear-wheel, cl, and at its center with a belt-drum, e, as represented.The frame A, at its rear portion, is also provided with standards, as atff, connected by a crosstie, f, at their top, from which tie brace-bars,as at f, extend downwardly and fixedly engage with the uprightsupports 1) b, as shown.

H H are hand-levers, which have their rear ends pivotally connected tothe standardsf f, as indicated in the figures, and F F are footlevers,the rear ends of which are in like manner connected with said standards.

I I are suitable connecting-bars, to connect the hand-levers to thecrank-shaft B, the upper ends of said bars being pivotallyconnected tothe respective hand-levers H H, as shown, while their lower ends areloosely confined by a metal strap, 9, to the wrist of a crank on thecrank-shaft B, as represented.

JJ are connecting-bars, respectively connected at their upper ends byloosely-fitting straps g to the wrist of a crank on the crank-shaft B,and at their lower ends are pivotally connected to their respectivefoot-levers F F, as represented in the figures.

The crank-shaft B, it will be seen, is provided with four cranks, all inthe same plane, two on each side of the center of the length of thecrank-shaft, at which center the banddrum e is applied, and that thecranks to which the bars I I J J are severally applied extend outwardlyin opposite directions to each other from the central axis of thecrank-shaft B, so that when the crank-shaft B is in the position shownin Fig. 3 the right foot-lever F will be at its lowest depression, whilethe right-hand leverH will be atits limit of upward throw, and the samerelations of the left-hand foot-lever F and the left-hand hand-lever Hare brought about when the crank-shaft B, in the operation of themachine, is made to assume the position shown in Fig. 2.

We will suppose, by Way of illustration of the operation of the motor,that the machine on the start has its several parts in the positionshown in Fig. 1, and that a man is standing with his right foot upon thelever F, his left foot upon the lever F, and with his right handgrasping the lever H and his left hand grasping the lever H. Theoperator now throws his whole weight upon his right foot, at the sametime lifting with all his might with his right hand. This act depressesthe right-handfoot-lever F to its lowest depression, while at the sametime the right-hand handlever H is drawn up to its greatest elevation,thereby producing a partial revolution of the crankshaft B. The momentumimparted to the balance-wheel 0 causes the crank-shaft B to pass itsdead-center during such partial revolution, whereupon the operator nowthrows his whole weight upon his left foot, which lightly rests upon thefoot-lever during the partial revolution just named, at the same timelifting with all his might upon the left'hand hand-lever H, therebyforcing apart the footlever F and hand-lever H into the positions shownin Fig. 2, thereby mostly completing a revolution of the crank-shaft.This done, and the momentum of the balance-wheel having caused thecrank-shaft to pass the dead-center of its mostly-completed revolution,the operator now again throws his weight upon the lever F, which then isin the position shown in Fig. 2, and also draws up with all his mightupon the hand-lever H, which then is in the position shown in Fig. 2,whereupon said foot and hand levers are forced apart until theyrespectively again occupy their positions, as

shown in Fig. 3, thereby completing somewhat more than one entirerevolution of the crankshaft B, and so on, in this manner, the weight ofthe operator and the strength of the operator are conjointly andsimultaneously utilized as a power for operating various kinds ofmachinery, which may be connected to the motor either by gearing thesame with the cog-wheel d or by a band around the drum P.

It will also be seen by reference to Figs. 2 and 3 that the combinationof the operative parts of the motor is such that when one handlever andone foot-lever are forced apart to their limit the opposite hand andfoot levers are caused to assume their nearest proximity; that said handand foot levers are forced apart in the line of vertical planes whichcorrespond with the limbs of a person operating the machine, and thusthat the combination of said levers is such as will afi'ord the greatestfacility for the exertion of the power of the operator, both as to hisweight and strength.

The power of the operator may be transmitted from the balance-wheel c bymeans of a round band running in a U-groove cut in the periphery of saidwheel, and the balance-wheel may also have proper appliances attached toit in order to operate a churn and other like machines.

I claim The combination of the crankshaft B, bars I 1, bars J J,foot-levers F F, and hand-levers H H, whereby the motor can be utilizedto simultaneously force the hand and foot levers apart in oppositevertical directions to 5 give rotation to the crank-shaft, substantiallyas described.
